## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Ionic Framework wraps the implementation around Capacitor's Keyboard
plugin API, to provide additional functionality and behavior
"automatically" in Ionic, when the plugin is installed.

Certain methods such as `getResizeMode()` are only available for certain
platforms and will cause an error when running in the unsupported
platform.

Ionic Framework does not check to see if that platform is active before
calling potentially unsupported methods, which leads to an exception for
scenarios such as this - calling `getResizeMode()` on Android.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Handles the uncaught exception by returning `undefined` if the plugin
method is unavailable.
- Developers do not receive an uncaught exception on Android when using
the Capacitor Keyboard plugin with Ionic Framework
